# If you notice that someone is iteratively editing a page (say by watching the IRC channel, or the [[Special:Recentchanges]] page) that you'd like to edit, consider waiting at least 10 minutes after the most recent edit before doing so, as the person iteratively editing the page may have further edits to make, and thus waiting a few minutes would likely save you both time by avoiding potential/likely edit conflicts.

# Avoid labeling proposals with people's names. Instead please label a proposal using a summary of some (perhaps unique) technical aspect of the proposal. The reasons for this are to avoid overly "personalizing" an idea and having the idea be judged (positively or negatively) by the author associated with it rather than the merits of the idea itself, to avoid having criticisms of the idea even remotely appear as if they are criticisms of the person, and to avoid having a specific person feel like they must defend attacks on an idea as if they were attacks on their person.

Please only create pages directly relating to POSH, microformats (and picoformats) on this wiki. data-portability in line with microformats principles is also encouraged. Other pages will likely be deleted.

Please do not use "?" or other punctuation in the headings - it helps to keep the URLs to their fragment identifiers shorter and easier to read, copy/paste etc.

Consider using lowercase words in headings (except for proper nouns), and avoid repeating the page title in headings. This helps with shortening permalinks to sections (thereby increasing fidelity of URL transfer, e.g. across email), and keeping their URLs all lowercase makes them easier to type.

Headings may be explicitly marked up with <h1> <h2> tags etc. in order to avoid having them show up / pollute the Table of Contents. If you find such headings in a page, please do not change them to "=" or "==" style headings.

Avoid renaming/changing heading text, including even just their capitalization or to comply with above rules that apply to headings. Headings are often used as permalinks, and changing the heading breaks such permalinks that have already been used. Thus be careful when creating headings. If you change a heading please leave a <div id="oldheadingID"></div> around the new heading with oldHeadingID set to the necessary value to maintain heading permalinks.

Avoid global editorial wiki changes / edits (e.g. the same or similar edits applied to numerous pages, say, more than a dozen or so pages). If you have an opinion on how to globally improve something stylistically or editorially on the wiki, please add it to your section on the to-do page, and then perhaps ask the community using the microformats-discuss mailing list what folks think of it. Interpret absence of response(s) as disinterest and thus implicit rejection. Admins may from time to time do global wiki changes to remove spam, repair damage done by other global wiki edits etc.

Please avoid simple contradictory responses such as "No" to questions and issues. Instead provide at least a short sentence with a reason which provides information beyond what is provided in the question or issue. Simple contradictions (like just inverting other statements on a page as if such an inversion was an argument), are a waste of time and space and to be avoided.

Do not remove "red links", nor create empty / placeholder "..." pages for them just to make them not red. The red links usefully communicate a need or a desire for that page to exist, and the person expressing that desire may not be the same person that is able to take the time, or has the necessary skill/background to draft such a page. The links to pages not yet created often serve as an effective (and easy to execute) "to do" list. Removing those links makes it harder, less convenient to do so. (One exception noted so far: red links to non-existent microformats e.g. "hbib", should be delinked, as it is desirable for it to be harder/less convenient to create new microformats). Finally, as such links do provide information, they are not redundant.

Do not use the MediaWiki "Categories" mechanism. As with "Talk" pages, this community does not use all the features of MediaWiki.

Do not create new "User:" links by hand. User: links should only created as a result of users actually signing their edits with ~~~ or ~~~~. That way each User: page will correspond to an actual login, rather than accidentally linking to a page which doesn't represent a login. If you see a red link which appears like it should be a User: link, e.g. [[DavidJanes]], rather than editing the link in place, create a redirect at the destination of the link to the person's User: page.

Check "what links here" before moving pages, and fix any links to the page you're moving, if appropriate.

References to (X)HTML element names should be lowercase and marked up with <code>...</code>, e.g. the input element. This convention is adopted from the practice used in the W3C Manual of Style.

Use example.org for hypothetical URL examples rather than a fake domain name (which may eventually be registered, used for spam etc.). When doing so, be sure to use <nowiki> tags, e.g.: <nowiki>http://example.org/</nowiki> so that the URLs are not auto-hyperlinked by MediaWiki. Where interactions between multiple domains need to be illustrated, you may use example.net or example.com or subdomains of example.org like foo.example.org.

Accessibility

Use upper case for acronyms like HTML but use <strong style="text-transform:uppercase"> to add strength to phrases like "do not". This improves accessibility (citation needed) for text-reading software and other agents (list and versions of text-reading software & other agents affected needed).
